(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) Fig. 2 is a sectional view taken on line 2-2 of v The invention described herein may be manufactured and used by or for the Government of the United States for governmental purposes without the payment to me of any royalty thereon in accordance with the provisions of the act of March 3, 1883 (Ch. 143, 22 Stat. L. 625) as amended by the act of April 30, 1928 (Ch. 460,y

45 Stat. L. 467).

This invention relates to bookstacks for libraries and, more particularly, to a structure for a bookstack in which the supporting members, claimed by my divisional application Serial Number 45,122, for the shelves themselves can be removed or replaced at will in order to create work or study spaces.

An object Aof the invention is to construct a library bookstack which will eliminate a large number of the structural columns which are conventionally used in the prior art.

A further object of the invention is to incorporate as an integral portion of the bookstack a Ventilating and air conditioning system to insure a constant circulation of conditioned air around and through the shelves at all times.

A still further object of the invention is the provision of improved support and suspension means for the partitions, of my aforementioned divisional application, supporting the shelves.

It is also an object of the present invention to provide means so that any portion of the stack, including the aisles, can be converted into locked enclosures.

Another object is to provide a structure for a system of shelving of universal size to accommodate either conventional rows of books or for the storage of large bound volumes of newspapers.

Another object is to utilize the space in certain stack columns as electrical Wire ducts.

Another object is to design a structure for a stack in which the accurate location of the supporting partitions for the shelves can be maintained independently of any variations in the structural members that may occur during construction.

In order to fully describe the structure claimed herein and one of its designed purposes it becomes necessary to also describe and illustrate the structure intended for conjoint use therewith, as claimed in my divisional application Serial Number 45,122.

In the drawings, Fig. 1 is a broken away View in perspective of a section of a complete bookstack installation.

Fig. 1.

Fig. 3 is a sectional View of a modiiied construction taken on line 2-2 of Fig. 1.

Fig. 4 is a plan view of the shelving adapted-4 for use in connection with the supporting structure claimed herein.

Fig. 5 is a detail elevation of the lower end of a suspended type of partition. Y

Fig. 6 is a side detail elevation of the top of at partition of the type shown in Fig. 5.

Fig. 7 illustratesla section in side elevation of a modified form of the structure shown in Figs. 5 and 6.

Referring to the drawings in detail, it will be $15 v The passageway between columns I and IA per- ;v

mits access to the shelves facing each other in the several sections.

The vertical I-beams of the columns I are preferably enclosed in sheet metal casings 4. of such a size as to permit inwardly tapered ducts 5 to be fitted in either open portion of the I-beam. At the various floor levels sheet metal collars 6 enclose the casings 4. These collars are formed with openings l registering with corresponding openings in the casing 4 and ducts 5.

Bearing against the longer sides of the collar 6, and tending to hold the collars in engagement with the casings 4, are spaced parallel angle beams 8 which extend along the whole series of columns I and IA. Between columns I and IA, and abutting the ends of the collars provided with openings l, are U-shaped troughs 9 which snugly fit between and are suspended from angle beams 8 and are closed across the top by floor plates 24. At regular intervals are nozzles or louvers I0 communicating with the troughs 9.

The alternate vertical columns IA are also provided with conduits 5A encased in a casing 4A similar to those of column I. Instead of the passageways of troughs .Il communicating with the passageways of the conduits, the columns IA have large registers II just above the floor levels communicating through the casings 4A with openings in the conduits 5a.

In practice, air, conditioned as desired -by any range, it will be observed that, while it is encased in a sheet metal casing I2, no Ventilating apparatus is contained therein, as in practice only one Ventilating column, either supply or eX- haust, is ordinarily necessary for each stack v@als @ist range. It is preferable to have the supply and exhaust columns adjacent the corridors between the ends of the ranges. These additional longitudinally aligned columns IB, however, are used completely concealing the vertical runs of elec-` Troughs 'trical wiring necessary for lighting.

9A, similar to the troughs 9, permit al1 wiring to becarried where desired, while the casings I2 allow the wiring to be carried from deck to deck.

The book shelving proper comprises a plurality of cast vertical partitions I3, equi-spaced between the range columns and each section holding adjustable shelves I4 as required. The shelves I4 are retained in fixed position by means of notches I5 vin the front edges of the partitions I3 and rear lugs I6, the latter being in vertical alignment near the middle line of the partitions. To rigidly hold the several partitions "of a series in position, angle bars l'I are tied to upper oiTset 'corner lugs i8, while the bottom corner'edges 0I the partitions are similarly tied by angle bars I9 to oliset bottom corner lugs 2,9.

The distribution of the weight on the shelves and partitions is a problem oi major importance and may be satisfactorily accomplished by. suspending the partitions i3 from the horizontal beams 2, as shown in Fig. 6, or by supporting the partitions on the floor directly above the beam 2, as shown in Fig. 7.

As disclosed in Fig. l, the upper edge of the partitions I3 are formed with a curved depression 2| near the middle to accommodate the horizontal girder 2. Integral lugs 22, having openings therethrough are cast near the top of the partitions and are bolted to the bottom flanges of the girder by bolts 23. As shown in Fig. l the bottoms of the partitions terminate several inches above the floor l LT55 24 so that the conditioned air may circulate under the stacks and also permit cleaning under the shelves.

If it is desirable to support the shelving directly on the floor, it may be readily done, as shown in Fig. 7, by forming the bottom edge of the partitions I3 with a depending central offset portion 23A which may be bolted through the floor plates '2K4 on either side of the beam 2. The top of the iloor supported partitions may be constrained by providing a cutaway section 25 at the center of the upper end in which girder 2 may lie, whereby angle plates 26 may be fastened to the top of the partitions and bolted to the web of the girder.

It is necessary to secure the ends of each stack section where the partitions I3 abut the vertical casings 4, 4A and I2. This end construction may take the form disclosed in either Figs. 2 or 3. In

Fig.V 2, the end partition I3 lies parallel to and slightly spaced .from the side wall of the casing.

The partition and casing may be retained in position by an angle bracket 2l bolted to the center of the bottom edge of the partition and to the vertical column.

The modied stack end illustrated in Fig. 3 makes use of an end partition I3A, to which the shelves are supported on hangers positioned in offset section 28, to form one side of a colurrmlv casing., An ornamental plate 3E) forms the opposite sider of the column casing which with side plates 29 and partition I3A completely encompass the ducts and I-beam.

As shown in Fig. 1, pivoted doors 3| may be hung on upper and lower angle bars I1 'and I9 using the holes 36 provided for this purpose in angle bars il and I9 so that a section of the range may be enclosed. If desirable, vthe end doors on opposite sides of the aisle may be fastened to one another to completely block 01T the entrance to the entire aisle.

Provision is made for horizontally dividing the vertical beams, casings enclosing the vertical v beams and forming columns, book-shelvesv supported by the horizontal beams between aligned columns, air ducts positionedv in said casings, and

louvered branch ducts connecting spaced columns,

each of said branch ducts being in fluid communication with at least one oi said air ducts.
